Details:
- Created a 'studies' subdirectory within 'test' to be used to house
test drivers, makefiles, run scripts, matlab plot code, and related
files that have been customized for collecting performance data on
specific host machines or product lines. This new setup will help us
catalog, track, and share test driver materials over time, and in a
way that facilitates reproducibility.
- Created an 'skx' subdirectory within 'test/studies' to house various
level-3 test driver files used to measure performance on SkylakeX
nodes (specifically, those nodes used by TACC's stampede2 system).
